Usually, pregnancy is not possible with high blood pressure, whether it is mild, moderate or severe, and can be dangerous for the child as well as for your own body. Mild hypertension can be managed well enough to allow pregnancy. Controlling mild hypertension requires attention to diet, lifestyle and medication, and pregnancy is possible when blood pressure is well controlled. If the patient has mild hypertension and must get pregnant, some medications need to be used, and once the medications are used, none of them are very safe for children without a little harm. However, some drugs are not very harmful, such as antihypertensive drugs have beta-blockers, metoprolol, etc. have less impact on children, but not absolutely safe, there is no indication that any of them are particularly safe, so mild hypertension pregnancy can have an impact on children and patients themselves, and is not very safe.
